Its all the fault of that Vast Evil Booster Seat Manufacturers Lobby!!
"Big Booster."
(actually, just more Big Government. Faugh.)
Maybe so. Some of these types of laws result at least partially from lobbying by manufacturers.
BTW, have you tried to buy a gas can lately? It seems like you can only find one brand and all their products are terrible. Apparently this results from a law that says gas cans must have spill-proof spouts.
